Also if there was a real zombie virus none of the movies so far have captured the sheer absolute terror of hard to defend transmission vectors like mosquitos, which would be likely to get the virus. Brings a whole new level of issues to not getting bit.

As science fiction is speculative, I do not fault any of those listed media however I feel none of them truly captured the sociopolitical insanity that would occur, the sheer level of ignorance and incompetence which causes anything that could go wrong, to go wrong.

We are headed towards: Hunger Games, Children of Men, Demolition Man, Judge Dredd, Escape from NY/LA
